Hi,
Finally, I managed to solve the MMS issue on my FP4 for french operator "Bouyges Telecom"!
After reading these post: https://forums.ubports.com/topic/10181/fp-4-without-mobile-data/4 and this one https://forums.ubports.com/topic/10464/how-to-fix-mms-issues, I gave it another try and found a working solution for both internet and SMS.

I did:

• Delete all existing APN settings
• Create a new APN setting with fields:
  • Internet and MMS
  • Name: Bouyges Telecom
  • acces: mms.bouygtel.com
  • MMSC: http://mms.bouyguestelecom.fr/mms/wapenc
  • And keep all other fields empty.
    Here is the screenshots with french language:
    

Hi,
I am working on an update of WifiTransfer app
You can see here a draft of layout

This is not so easy to make clear information for user. I tried!

Feedback is welcomed!

Hello @ezst036
I see the same settings as you: 16:9 8.3MP (or 4:3 12MP), and I did not find how to have a higher resolution.

Hi,
I have the same problem on FP4: headphones via usb-c does not work.
I see there is an issue on it: https://gitlab.com/ubports/development/core/packaging/usb-moded/-/issues/6

I hope, it could be fixed soon!

Thanks @bhdouglass, shoutcast-ut being in github, that would be too much work and time for me to apply it. But for sure this will be really useful for other apps!

@wdehoog, I have tagged my fork of your source code with v0.6 and have uploaded the click package here https://github.com/Ublublu/shoutcast-ut/releases/tag/v0.6.
So if you agree you could upload it in the open store for focal.

Hi,
I have ported an app (shoutcast-ut) for focal. It is not my app but the one of wdehoog, I did a pull request on his source code. But wdehoog has no more the possibility to build the app.
You can see details in the pull request here: https://github.com/wdehoog/shoutcast-ut/pull/22

On my side I can build and publish an app. I think it would be useful to make the app available to all users.
I could send the click packages to the maintainer and if he accepts he could upload it.
or with approval of maintainer, can we have several publisher for an app on openstore ?
or any other suggestion to manage such situation?

@domubpkm yes I noticed that it has to be checked.
Better to be sure, thanks for the precision!

@domubpkm I have retried your proposed settings, even with rebooting the phone to be sure settings are taken into account. And it gave no results, still no internet and no MMS.
The best I succeed is what I proposed in last screenshot for internet only. I tried many things for MMS, I never succeed.
I find quite strange that default settings does not work since they are compliant with what recommends the "Bouyges Telecom" provider.
May be I will later try in Android.

The NOT working APN settings, which are given by reinit of settings, in 20.04 OTA 3:

The working APN settings, which are given by reinit of settings, in 16.04 OTA 25:

In 20.04OTA3, I erase the two default not working settings, and create two new ones equal to the ones of OTA 25. I reboot the phone and enable mobile data, it works!

Problem solved for internet!
not yet for MMS! probably APN settings are incorrect, I would need to set MCC, MNC, APN type as it was previously mentionned here: https://forums.ubports.com/topic/5615/how-do-you-set-the-apn-settings-for-mcc-mnc-and-apn-type?_=1701009468487 but this post does not help so much.

How can we manage these settings MCC, MNC, APN type within UT?

Then on FP3+, I switched to 20.04 stable channel and upgraded. I have now OTA 3 and mobile data are working. I see that I have the exact same APN settings than with 1604 OTA25.

So the problem is with default apn settings when reseting them, they are:

• OK on 16.04
• KO on 20.04

Problem solved for internet, I need to enter manually the APN settings.

I will give the details of the settings in a next post.

News!!!

Since on my old FP2 (16.04 OTA 25), mobile data were running perfectly, I reinstall 16.04 OTA 25) on my FP3+ (which was with 20.04 OTA 3) and mobile data are working!

So I think we can suspect a regression in 20.04.

so try to find the scenario:

• I was with my FP3+ on 16.04 OTA 25 and french operator "Sosh" (SIM1): mobile data OK
• I switch to 20.04 OTA 2, then 3: mobile data ok
• I change operator to "Bouygues Telecom" (switch "Sosh" in SIM2 and put "BouyguesTelecom" in SIM1): mobile data KO on both SIM1 or SIM2.
• then I had only "Bouygues Telecom" in SIM1, and I never succeed to make running mobile data
• finally switch back to 16.04 OTA 25 -> mobile data comes back.

@domubpkm , yes I try also with 2G/3G, it does not work.

Before re-installing Android and UT, I did a few test by launching some scripts in /usr/share/ofono/scripts:

• disable-gprs
• enable-gprs

then

• disable-modem
• enable-modem

But it did not bring back the mobile data !

When I enable mobile data, I often notice but not always, that network icon (use for wifi) was flickering between three dots and empty. After the scripts disable-gprs/enable-gprs, the tree dots appears a longer time, I take a snapshot:

Thank you @RedXXIII , I will try as you propose to reinstall Android (without sim card) and then UT.

Thanks @domubpkm
I have a look at it. It brings me to get information from ofono on my FP3+:

phablet@ubuntu-phablet:/usr/share/ofono/scripts$ ./list-contexts
[ /ril_0 ]
    [ /ril_0/context1 ]
        Name = Bouygues Telecom
        Active = 0
        Preferred = 1
        Type = internet
        Protocol = ip
        AccessPointName = mmsbouygtel.com
        Username =
        Password =
        AuthenticationMethod = any
        MessageProxy = 62.201.129.226:8080
        MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
        Settings = { }
        IPv6.Settings = { }

    [ /ril_0/context2 ]
        Name = MMS
        Active = 0
        Preferred = 0
        Type = mms
        Protocol = ip
        AccessPointName =
        Username =
        Password =
        AuthenticationMethod = any
        MessageProxy =
        MessageCenter =
        Settings = { }
        IPv6.Settings = { }

    [ /ril_0/context3 ]
        Name = IMS
        Active = 0
        Preferred = 0
        Type = ims
        Protocol = ip
        AccessPointName =
        Username =
        Password =
        AuthenticationMethod = any
        Settings = { }
        IPv6.Settings = { }

[ /ril_1 ]

then the same on my old FP2 with same sim card, and with mobile data working correctly:

phablet@ubuntu-phablet:/usr/share/ofono/scripts$ ./list-contexts
[ /ril_1 ]
[ /ril_0 ]
    [ /ril_0/context1 ]
        Settings = { Gateway=100.89.218.180 Method=static DomainNameServers=62.201.129.202,62.201.129.201, ProxyPort=8080 Interface=rmnet0 Proxy=62.201.129.226 Address=100.89.218.179 Netmask=255.255.255.0 }
        Name = Bouygues Telecom
        Preferred = 1
        Type = internet
        Username =
        Password =
        Protocol = ip
        AuthenticationMethod = chap
        AccessPointName = mmsbouygtel.com
        MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
        IPv6.Settings = { }
        MessageProxy = 62.201.129.226:8080
        Active = 1

    [ /ril_0/context2 ]
        Settings = { }
        Name = Bouygues MMS
        Preferred = 0
        Type = internet
        Username =
        Password =
        Protocol = ip
        AuthenticationMethod = chap
        AccessPointName = mmsbouygtel.com
        MessageCenter = http://mms.bouyguestelecom.fr/mms/wapenc
        IPv6.Settings = { }
        MessageProxy = 62.201.129.226:8080
        Active = 0

I have no competencies on ofono, but I see a difference which seems to me abnormal:
For [ /ril_0/context1 ] on FP3 and FP2, it corresponds to the APN setting I have configured and activated, but Active = 0 on FP3 and Active = 1 on FP2. And another difference is that Settings is empty in FP3 and filled in FP2.

Thanks of lot if someone has an idea of what to do, for example is there an ofono script (in /usr/share/ofono/script) with which I could try a re-initialization or configuration?

I update to dev channel on 20.04, version 261. But no success, still no mobile data!

Thanks @domubpkm , I try on sim1 and sim2 but nothing change!

I try my sim card on my old FP2, and mobile data works directly without any change in parameters.
I then check that I have same parameters between FP2 and FP3. And it does not work on FP3.

Thank you @Lakotaubp , I set only internet (no MMS), but no change still not working, even after a reboot.

Thanks @Keneda , I did it but it is still not working.

Hi,
I have the same problem of mobile data not working.
I have a FP3+ with UT20.04 (OTA3 stable).
I switch from operator (in France, from Sosh to BouygesTelecom). With the previous operator (Sosh), mobile data were working without issue.
When I receive my new SIM card, I installed it in slot SIM1 and move the old SIM from previous operator in SIM2. From that time mobile data were not working either on SIM1 neither on SIM2 (during a few days the two operators were operational for the transition). I try to switch mobile data from sim1 to sim2 several times in APN settings, but it never works.
When my previous operator stops, I remove the old SIM card.
But now with one sim card, it also does not work! Phone calls ans SMS works. I notice that symbol L is not display in the top bar, it is displayed only in the SIM1 field next to operator name.
note: the battery drain was significantly higher than usual, it drops in one day.
I try:

• to reboot,

• to move sim card from slot1 to 2, reboot, and switch back again,

• and also to reset APN settings several times

• check APN settings from operator (found here https://www.assistance.bouyguestelecom.fr/s/forum/question/0D5080000BUOq8yCQD/comment-paramétrer-lapn-de-mon-téléphone-

  Nom = Bouygues Telecom
  APN = mmsbouygtel.com
  Proxy = non défini
  Port = non défini
  Nom d’utilisateur = non défini
  Mot de passe = non défini
  Serveur = non défini
  MMSC = http://mms.bouyguestelecom.fr/mms/wapenc
  Proxy MMS = 62.201.129.226
  Port MMS = 8080
  MCC = 208
  MNC = 20
  Type d’authentification = PAP
  Type d’APN = default,supl,mms
  Protocole APN = IPv4 (ne pas choisir IPv6)
  Protocole d’itinérance APN = IPv4 (ne pas choisir IPv6)
  Support = non défini
  Type d’opérateur du réseau virtuel mobile = aucun

It is correct (except that from the line MCC above, these are not parameters we can find in UT)

@Keneda how do you delete APN settings when you have no SIM card? in that case, the cellular menu is empty, it only says "no sim card".

So now I don't know what to do!
Thanks if you have an idea
